White Fuzz on Seedlings
Answered by: Ginny Cotterill
Question from: Gail
Posted on: October 22, 2012

I attended a seminar last Saturday and we sowed some Swiss Chard seeds. After some of the seeds germinated I took off the plastic cover only to discover that the seeds that were up were growing white fuzz. Not all came up but some are pushing through the soil. What should I do to salvage the rest of the tray?

The white fuzz is most likely a fungus that grows on the soil-less media and vermiculite, when conditions are moist and warm. The remedy now is to keep the plastic lid off so that air circulates, and the humidity level around the seedlings moderates. The remaining seedlings should continue to grow and thrive. I hope you have great success with your Swiss Chard.
